  • Drive Shank: 25/64 Inch (10mm), Drill Size: 9/32 Inch (7mm), Counterbore Size: 1/2 Inch, Drill Length: 4 Inch, Counterbore Length: 15/16 Inch
  • Professional Finishing: A flat countersunk drill bit creates a clean, professional finish for woodworking projects. The recessed hole seats the screw head neatly, enhancing the appearance. Moreover, the counterbore center hole provides a slightly larger space than a 1/4" screw, allowing you to make fine adjustments before locking two workpieces together.
  • Compatible with Styles of 1/4" Screws: Flat countersink drill bits are versatile and work well with various screws, including furniture screws, round screws, and even some socket-head screws. This versatility makes them suitable for a wide range of projects.
  • Simplified Drilling Process: A counterbore drill bit combines two steps into one – drilling the recessed hole and the through hole – which saves time and effort during the drilling process. This drill bit ensures the inner and outer holes are perfectly concentric.
  • Reduced Splitting: When fastening materials like wood, using a flat countersink drill bit helps prevent the wood from splitting.
